My Challenger has two black tanks and two grey tanks. Each black/grey set of tanks has its own outlet and hose must be moved or get two hoses with a wye which is what I have. If you don't have a grey mid tank, then I would dump that one first, then move to the rear set and use that rear grey tank to flush your hose out. The Saniflush also does a good job of cleaning the tank and hose.
